云南省处于我国南北地震带的南端.该省新构造运动剧烈,地震活动频繁.同时,这里与西藏高原接壤,地下构造颇为复杂.因此,我们收集了该省的地磁短周期变化资料,并进行了初步分析.所得结果表明,云南省地磁短周期变化存在着异常.其表现为:西北自丽江向东南经下关、楚雄到通海,有一条西北-东南的分界线.此线的东北与西南,地磁湾扰、磁暴急始等短周期事件垂直分量的变化△z 呈现反号.由此推断,在该省地下存在着自西北到东南走向的电导率异常带.最后,简单讨论了与高导带存在有关的其他地球物理现象. Yunnan Province is located at the southern end of the North-South Seismic Belt in China. The province has a tremendous new tectonic movement and frequent earthquakes, and here the border with the Tibetan Plateau is quite complicated. Therefore, we collected data on the geomagnetic short- The results show that there are some anomalies in the geomagnetic short-period variation in Yunnan Province, which are as follows: the northwest from Lijiang to the southeast through Xiaguan, Chuxiong to the sea, there is a dividing line between northwest and southeast. The variation of the vertical component of short-period events such as southwestern, geomagnetic disturbances and storms in the first period shows the sign of inversion, which indicates that there is an anomalous zone of conductivity in the province from northwest to southeast.Finally, There are other geophysical phenomena associated with high conduction bands.
